Sonoff 4CH Pro - Non-mains switching at last

After my 4CH video, this is the 4CH Pro video. It will be very similar, most of the differences for me are in the electrical connections: this is the device if you want to control garage door openers, furnaces, sprinklers or any other devices that run on DC or require dry contact.
